TESA
At Eva IVF & Women’s Centre, we recognize that fertility is a shared journey, and male subfertility deserves just as much attention, care, and innovation as female reproductive health. For men with obstructive or non-obstructive azoospermia (absence of sperm in the ejaculate), TESA (Testicular Sperm Aspiration) offers a breakthrough method to retrieve viable sperm directly from the testicles — giving couples the opportunity to pursue parenthood through ICSI or IVF.
If you’ve been told that sperm are absent in your semen, don’t lose hope. With TESA, biological fatherhood is still within reach.
What is TESA?
TESA (Testicular Sperm Aspiration) is a minimally invasive outpatient procedure that involves aspirating sperm directly from the testicular tissue using a fine needle. It is commonly performed in cases of:
• Azoospermia (no sperm in semen)
• Failed vasectomy reversals
• Obstructive blockages in the vas deferens or epididymis
• Congenital absence of vas deferens
• Non-obstructive azoospermia with focal sperm production
💡 TESA provides access to genetically linked sperm for men who otherwise have no sperm in their ejaculate — and eliminates the need for major surgery.
Who Should Consider TESA?
TESA is ideal for men who:
✔ Have been diagnosed with azoospermia
✔ Are planning ICSI (Intracytoplasmic Sperm Injection) as part of their IVF cycle
✔ Have had a failed vasectomy reversal
✔ Suffer from blockages in the reproductive tract
✔ Cannot ejaculate due to spinal cord injuries or certain health conditions
✔ Want to preserve fertility before cancer treatments
💡 TESA is often the first-line sperm retrieval method for azoospermic men undergoing assisted reproduction.
How Does the TESA Procedure Work? (Step-by-Step Overview)
1. Pre-Procedure Assessment
• Scrotal ultrasound to assess testicular structure
• Genetic and infection screening, if required
• Counseling and planning of the ICSI/IVF cycle alongside female partner's treatment
2. On the Day of the Procedure
• A fine needle is inserted through the scrotal skin into the testis
• A small amount of testicular tissue is aspirated
• The sample is processed in our embryology lab to extract and isolate viable sperm and it can be used fresh or frozen for future use.
⏱️ Duration: 20–30 minutes
🏥 Hospitalization: Not required (same-day discharge)
💡 The procedure is comfortable, quick, and causes minimal disruption to daily life.
Benefits of TESA
🌟 Simple, outpatient procedure with no need for cuts or stitches
🌟 High success rate in retrieving sperm in cases of obstructive azoospermia
🌟 Preserves fertility without hormonal medications
🌟 Can be repeated or combined with other retrieval techniques (e.g., TESE or Micro-TESE)
🌟 Enables biological fatherhood for men with no sperm in their semen
Success Rates and Fertility Outcomes
📊 At Eva IVF, our clinical experience and research-backed approach offer:
✔ 90–95% sperm retrieval success rate in obstructive azoospermia
✔ 40–60% success in certain cases of non-obstructive azoospermia
✔ Excellent fertilization and embryo development rates when combined with ICSI
✔ Comparable pregnancy rates to standard IVF cycles using ejaculated sperm
💡 Every case is different, and our team tailors your treatment plan to maximize outcomes.
Post-Procedure Care & Recovery
✔ Mild soreness or swelling at the aspiration site is normal
✔ Avoid lifting heavy weights or intense activity for 2–3 days
✔ Pain medications are prescribed if needed
✔ Resume normal routines within 24–48 hours
✔ A follow-up consultation is arranged to discuss sperm quality and next steps
💡 Many patients return to work the next day with little or no downtime.
